Interesting info:
While I was looking for reference images, apparently when one teeth grows long - the head start growing asymmetrical.
What I didn’t know: on rare cases both front tooth develops into tusks. I bet it is not without any pain to be a Narwhal.

The fun thing is that narwhal tusks aren’t just long teeth like say elephant ivory is, they’re also kinda like enamel-crusted whiskers.
True :)
It is fascinating how evolution works with these kinda useless extras.
